It restores cordless operation to units where the original cell has lost capacity or failed outright. Voltage and capacity match the OEM specification exactly — 10.8V, 3000mAh (32.4Wh).\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOT-701, OT-707, and OT-601 fitment:\u003c\/strong\u003e\n    These three models share the same battery bay geometry, connector pinout, and BMS communication protocol, which is why one cell covers all three. The 9N-1200SCK form factor fits all variants without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on the OT-701 platform. The BMS accepted the cell without fault flags, completed its initialization handshake, and held voltage within the acceptable window across a full discharge curve.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation self-test protocol:\u003c\/strong\u003e\n    After fitting this battery, allow the infusion pump to complete its full power-on self-test without interruption. JMS pump firmware runs a BMS verification sequence at startup — cutting power during this window triggers a persistent battery fault that will not clear until the device completes a clean reboot cycle.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice not completing boot sequence on first use with a new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe JMS OT-701's BMS runs a chemistry verification check at startup. A new Ni-MH cell that has partially self-discharged during storage may present a resting voltage below the threshold the pump expects at boot. The firmware interprets this as a fault and halts the startup sequence before the device reaches the main screen. Charge the battery to full before the first installation — do not insert it directly from packaging and attempt to boot.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLow battery alarm triggering immediately after a confirmed full charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens because the OT-701's BMS compares internal resistance readings against thresholds calibrated for a conditioned cell. A brand-new Ni-MH cell has not completed its break-in cycle, so internal resistance reads higher than the BMS expects from a healthy battery. The pump alarm fires based on resistance, not just voltage — which is why the alarm appears even when the cell is fully charged. Run one complete charge-discharge cycle on the device before clinical use; resistance drops to within spec and the alarm clears.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381499330650,"sku":"BWCS-JSP701MD-1","price":77.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381499363418,"sku":"BWCS-JSP701MD-2","price":90.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381499396186,"sku":"BWCS-JSP701MD-3","price":100.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-JSP701MD-1.webp?v=1778901266","url":"https:\/\/batteryweb.com\/products\/jms-ot-701-replacement-battery-108v-3000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
